MuchBoost B48B20B/B46B20B Upgraded Turbocharger with a Custom Billet Compressor Wheel 6+6 Blades and a Clipped Turbine Wheel.  It is based on an original Garrett Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Toyota Supra MK5, BMW M135i F40, M235i F44, X2 M35iX F39, 330i G20, 530i G30, 630i G32, 730i/740e G11, Z4 G29, Mini Clubman F54, and Countryman F60 with the B48B20B/B46B20B 258-302HP engines.

The turbo delivers up to 155% power (142 extra HP) over the factory specs. It is a great choice for someone looking to match the power of B48’s big brother, the B58. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.

We have developed 2 modification options that allow you to reach anywhere from 360HP to 400HP.
